Need something to support your knee

Hey guys, I’m trying to get my knees lifted while lying on my back. Is there anything that can help keep your legs apart and lifted so I can free my hands to do other things? I’ve tried using the njoy pure wand with alternating hands and then both hands when I get tired so I’m looking for something that can help me lift my legs. I haven’t had much luck lying on my back or side.
